Hello, I have a 2011 1500 hemi sport 3:92 LSD rear end. My truck came with the 275/60R20 i changed them to 275/55R20 new tires are about an 1" shorter. So after the install of the new tires the truck had more get up and go. I need new tires now and was thinking about putting on the 275/60R20 it's a better ride with the taller tires. I did a quick caculation with my current tires the trucks gear ratio is about 4:10. I want to upgrade the my gears now but i think i want maybe 4:30 but can not find them for the 2011 Hemi any help guys.
